Description

Technical Field

[0001] This utility model relates to the field of ink return blades, and more particularly to ink return blades with adjustable length. Background Technology

[0002] As a key component in screen printing, the ink return blade plays a crucial role, directly affecting the paste distribution, printing quality, and efficiency in photovoltaic cell production. With the rapid development of the photovoltaic industry, especially the diversification of cell sizes and the increasing demands for production efficiency, the design and application of the ink return blade face more challenges. Understanding the background technology of the ink return blade is of great significance for optimizing the photovoltaic cell production process and improving product quality.

[0003] Existing technologies, such as the utility model patent with publication number CN205736357U, disclose an ink return blade. This patent includes an ink return blade body, with ink return blade terminals attached to both sides of the ink return blade body. The ink return blade terminals are rotatable relative to the ink return blade body. In the ink return blade provided in this utility model embodiment, the ink return blade terminals are rotatable relative to the ink return blade body, thereby allowing the ink located on the side of the ink return blade to return to the printing area under the action of the ink return blade terminals.

[0004] In the existing technology, when adjusting the length of the two ink return blades inside the connecting plate, the connecting plate is not fixed, which makes it easy for the ink return blades to shift during use. This affects the stability and consistency of the ink return blades when the ink is spread evenly. This instability can easily lead to uneven ink distribution, which in turn affects printing quality and efficiency, and reduces the reliability of the overall production process. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when adjusting the length of the two ink return blades inside the connecting plate, the connecting plate is not fixed, which causes the ink return blades to easily shift during use. This affects the stability and consistency of the ink return blades when the ink is spread evenly. This instability can easily lead to uneven ink distribution, which in turn affects printing quality and efficiency and reduces the reliability of the overall production process. The invention proposes an adjustable-length ink return blade.

[0007] The effect achieved by the above components is that the connecting plate and the baffle base can be easily fixed by setting the adjustment structure, which avoids the phenomenon that the connecting plate is easy to move during the use of the ink return knife body, thereby improving the stability and reliability of the ink return knife body during use.

[0008] Preferably, the limiting block has anti-slip textures on both sides, and the anti-slip textures are evenly distributed on the limiting block.

[0009] The effect achieved by the above components is that the anti-slip texture can increase the friction of the limit block, preventing the user's hand from slipping when rotating the limit block.

[0010] Preferably, the arc surface of the connecting rod is fitted with two coil springs, and the two ends of the coil springs are fixedly connected to the limiting plate and the fixing seat, respectively.

[0015] The effect achieved by the above components is that the ink return knife body can be easily replaced by setting up auxiliary structures, thereby improving the replacement efficiency of the ink return knife body and thus improving the overall working efficiency and production capacity of the production line.

[0016] Preferably, two auxiliary plates are fixedly connected to one side of the ink return blade body, and the auxiliary plates and the fixed plates are slidably connected.

[0017] The effect achieved by the above components is that the auxiliary plate can position the fixing plate, making the fixing plate more secure.

[0018] Preferably, a guide block is fixedly connected to one side of the positioning block.

[0019] The effect achieved by the above components is that, due to the small size of the guide block, the fixing plate can be easily inserted into the positioning block.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 The adjustable ink return blade provided in this embodiment includes: two ink return blade bodies 1 and an auxiliary structure 8. The same connecting plate 2 is installed on the side of the two ink return blade bodies 1. A fixing plate 3 is installed on one side of the ink return blade body 1 with the help of the auxiliary structure 8. The same baffle base 4 is slidably connected to one side of the two fixing plates 3. A screw 5 is installed on one side of the fixing plate 3. Two mounting plates 6 are fixedly connected to one side of the baffle base 4. An adjustment structure 7 is provided on one side of the baffle base 4. An auxiliary structure 8 is provided on one side of the fixing plate 3.

[0027] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjustment structure 7 includes an adjustment plate 712, which is fixedly connected to the baffle base 4. Two fixing rods 708 are slidably connected to the inner wall of the adjustment plate 712. The fixing rods 708 are fixedly connected to the connecting plate 2. A grooved plate 707 is fixedly connected to one side of the adjustment plate 712, and a fixing seat 701 is fixedly connected to one side of the connecting plate 2. A connecting rod 702 is rotatably connected to the inner wall of the fixing seat 701. A limiting plate 703 is fixedly connected to the arc surface of the connecting rod 702. An auxiliary groove 704 is provided on the inner wall of the limiting plate 703. The limiting plate 703 and the grooved plate 707 are slidably connected. A screw 705 is fixedly connected to the inner wall of the fixing seat 701. A limiting block 706 is threadedly connected to the arc surface of the screw 705. The limiting block 706 abuts against the limiting plate 703. By setting the adjustment structure 7, the connecting plate 2 and the baffle base 4 can be easily fixed, preventing the ink return knife body 1 from being used... During use, the connecting plate 2 is prone to movement, thereby improving the stability and reliability of the ink return knife body 1 during use. The limiting block 706 has anti-slip textures 709 on both sides, which are evenly distributed on the limiting block 706. The anti-slip textures 709 can increase the friction of the limiting block 706 and prevent the hands from slipping when the limiting block 706 is rotated. The arc surface of the connecting rod 702 is fitted with two coil springs 710. The two ends of the coil springs 710 are fixedly connected to the limiting plate 703 and the fixed seat 701 respectively. The coil springs 710 can increase the torsional force of the limiting plate 703, making the limiting plate 703 more convenient to use. A handle 711 is fixedly connected to one side of the limiting plate 703. The cross section of the handle 711 is "U" shaped. The handle 711 can drive the limiting plate 703 to rotate, achieving the effect of convenient control of the limiting plate 703. In the embodiments of this utility model, please refer to Figure 4 and Figure 5The auxiliary structure 8 includes a mounting frame 801, which is fixedly connected to a fixing plate 3. Two telescopic rods 802 are fixedly connected to the inner wall of the mounting frame 801. Insert blocks 803 are fixedly connected to the ends of the two telescopic rods 802 that are far apart from each other. Springs 804 are fitted onto the arc surfaces of the telescopic rods 802, and both ends of the springs 804 are fixedly connected to the mounting frame 801 and the insert blocks 803, respectively. Two positioning blocks 805 are fixedly connected to one side of the ink return knife body 1. Positioning blocks 805 and fixing plate 3 are slidably connected, and positioning blocks 805 and insert blocks 803 are slidably connected. A moving plate 810 is fixedly connected to one side of the insert blocks 803. Several limiting rods 807 are slidably connected to one side of the mounting frame 801. The side of the limiting rod 807 is fixedly connected to the same positioning plate 806. The positioning plate 806 and the moving plate 810 are slidably connected. By setting the auxiliary structure 8, the ink return knife body 1 can be easily replaced, improving the replacement efficiency of the ink return knife body 1, thereby improving the overall working efficiency and production capacity of the production line. Two auxiliary plates 809 are fixedly connected to one side of the ink return knife body 1. The auxiliary plates 809 and the fixed plate 3 are slidably connected. The auxiliary plates 809 can position the fixed plate 3, making the fixed plate 3 more firmly fixed. A guide block 808 is fixedly connected to one side of the positioning block 805. Since the guide block 808 is small in size, the fixed plate 3 can be easily inserted into the positioning block 805. The working principle of the adjustable ink return knife provided by this utility model is as follows: By setting the adjustment structure 7, the connecting plate 2 is moved first, driving the ink return knife body 1 to move. When the connecting plate 2 moves, it also drives the fixing rod 708 to insert into the interior of the adjustment plate 712. Then, the limiting plate 703 is rotated with the help of the handle 711, so that the limiting plate 703 drives the connecting rod 702 to rotate inside the fixed seat 701. At the same time, the auxiliary groove 704 of the limiting plate 703 passes through the screw 705 and the limiting block 706 until the limiting plate 703 is inserted into the groove plate 707. Then, the limiting block 706 is rotated with the help of the anti-slip texture 709, so that the limiting block 706 is fixed to the fixed seat 701. At the same time, the limiting block 706 just blocks the auxiliary groove 704. At this point, the connecting plate 2 and the baffle base 4 are fixed. Then, the ink return knife body 1 inside the connecting plate 2 can be moved. When the ink return knife body 1 moves, it will also drive the auxiliary structure 8 to move. The auxiliary structure 8 will drive the fixing plate 3 to move inside the baffle base 4. When the ink return knife body 1 moves to the appropriate position, turn the screw 5 to fix it. At this point, the position of the ink return knife body 1 is fixed. Then, use the mounting plate 6 to install it in the appropriate position. The anti-slip texture 709 can increase the friction of the limit block 706 and prevent the person's hand from slipping when rotating the limit block 706. The coil spring 710 can increase the torsional force of the limit plate 703, making the limit plate 703 more convenient to use.

[0028] By setting the auxiliary structure 8, the fixed plate 3 is first moved and inserted into the positioning block 805. Then, the moving plate 810 is released. Due to the action of the spring 804, the insert 803 will move inside the mounting frame 801. While moving, the insert 803 will also drive the telescopic rod 802 to stretch until the insert 803 is inserted into the positioning block 805. Then, the positioning plate 806 is moved to drive the limiting rod 807 to be inserted into the mounting frame 801, so that the positioning plate 806 positions the moving plate 810 to prevent the moving plate 810 from moving. At this time, the installation of the ink return knife body 1 and the fixed plate 3 is completed. Since the guide block 808 is small in size, the fixed plate 3 can be easily inserted into the positioning block 805. The auxiliary plate 809 can position the fixed plate 3, making the fixed plate 3 more firmly fixed.
